And what about the init functions which are called? Or other cases in the 
code which iterates over hwaccels? Have you tried if accelerated 
processing works after your patch?

Thanks,

Yes, I have tested OK with both videotoolbox decode and encode,
ffmpeg_opt.c:842 will invoke av_hwdevice_find_type_by_name(hwaccel); 
to get them. For cuvid isn't defined in the hwcontext.c, so keep it
anyway.

The loop in ffmpeg.c:2845 won't find the hwaccel if you remove them from 
this list.

I understand ffmpeg.c 2824 config will true if it's expected, so it'll not come to ffmpeg_opt.c:842.
